# The distutils eclass is designed to allow easier installation of
# distutils-based python modules and their incorporation into
# the Gentoo Linux system.
#
# - Features:
# distutils_src_compile()    - does python setup.py build
# distutils_src_install()    - does python setup.py install and install docs
# distutils_python_version() - sets PYVER/PYVER_MAJOR/PYVER_MINOR
# distutils_python_tkinter() - checks for tkinter support in python
#
# - Variables:
# PYTHON_SLOT_VERSION     - for Zope support
# DOCS                    - additional DOCS
